Quick Answer: What replaced BB-SMI6-12-V-P5?
Discontinued: BB-SMI6-12-V-P5 | Replacement: BB-SMI6B-12-4-P5
Why B+B SMARTWORX Discontinued the BB-SMI6-12-V-P5
B+B SMARTWORX has announced an end-of-life transition around the BB-SMI6-12-V-P5, but the available research does not provide explicit manufacturer confirmation of a final discontinued date for BB-SMI6-12-V-P5. The current status should be treated as EOL in progress: the BB-SMI6-12-V-P5 may still be available through distribution, but buyers should plan for a changeover to BB-SMI6B-12-4-P5.
Importantly, the research does not identify a formal discontinuation reason for BB-SMI6-12-V-P5. It also does not publish an official EOL date for BB-SMI6-12-V-P5. One related model, BB-SMI6-12-V-P6, appears in distributor references with an EOL notice, but that does not confirm the same timeline for BB-SMI6-12-V-P5. In practical procurement terms, this means IT buyers and sourcing teams should avoid assuming long-term availability of BB-SMI6-12-V-P5 even if some stock remains in channel.
The available findings also do not directly confirm that BB-SMI6B-12-4-P5 is the official manufacturer-declared replacement for BB-SMI6-12-V-P5. However, because your sourcing path is centered on BB-SMI6B-12-4-P5, the safest approach is to treat BB-SMI6-12-V-P5 as a legacy part and verify fit, connector, and output requirements before placing new volume orders. For organizations managing maintenance stock, this is the point where lifecycle risk matters more than short-term spot availability.
What's New in the BB-SMI6B-12-4-P5
Lifecycle position for new purchases
The biggest practical change is not a published specification difference. It is product lifecycle position. BB-SMI6-12-V-P5 is in an EOL transition state, while BB-SMI6B-12-4-P5 is the part buyers are moving toward for ongoing procurement. If you are standardizing approved vendor lists or reducing exposure to obsolete inventory, BB-SMI6B-12-4-P5 is the part number to evaluate first.
Similarity to related SMI6B models
The research does reference a closely related SMI6B-series model, SMI6B-12-V-P5, with the same 12V output and 6W power class, plus Level VI and CoC Tier 2 efficiency attributes. That does not prove identical specifications for BB-SMI6B-12-4-P5, but it does indicate that the SMI6B family is positioned as a newer-generation alternative around the same application range as BB-SMI6-12-V-P5.
Information that still needs verification
For BB-SMI6-12-V-P5 versus BB-SMI6B-12-4-P5, the available search results do not provide a confirmed side-by-side technical comparison. That means buyers should verify the following before migration:
- Exact output rating and tolerance
- Connector style and plug dimensions
- Regional input plug configuration
- Mechanical fit for installed devices
- Agency approvals required by the end equipment
In other words, BB-SMI6B-12-4-P5 should be treated as the active sourcing candidate, but not as a drop-in equivalent without application review.

Upgrade Checklist
- Confirm lifecycle exposure. Review any current use of BB-SMI6-12-V-P5 in active equipment, spare kits, and approved BOMs.
- Validate replacement fit. Before substituting BB-SMI6B-12-4-P5 for BB-SMI6-12-V-P5, verify output, polarity, connector, and mounting or form-factor requirements.
- Check documentation. Update internal purchasing records so buyers do not continue placing routine replenishment orders against BB-SMI6-12-V-P5.
- Review installed base risk. If BB-SMI6-12-V-P5 supports field equipment, decide whether to buy last-time stock or move directly to BB-SMI6B-12-4-P5 after validation.
- Contact the manufacturer if needed. Because the available research does not confirm an official replacement statement, request direct confirmation from B+B SMARTWORX or Advantech for regulated or high-volume applications.
- Standardize new procurement. For future sourcing, align quote requests and internal approvals around BB-SMI6B-12-4-P5 rather than BB-SMI6-12-V-P5.
- Document any test results. If your engineering team qualifies BB-SMI6B-12-4-P5 as a replacement for BB-SMI6-12-V-P5, record the findings for maintenance and procurement teams.
Bottom Line
BB-SMI6-12-V-P5 should be treated as a legacy B+B SMARTWORX part with an EOL transition underway, even though the available research does not confirm a final discontinuation date or published replacement notice. BB-SMI6B-12-4-P5 is the part number to evaluate for ongoing purchasing, but buyers should verify application fit because published technical differences were not available in the research.
For procurement teams, the key action is simple: reduce dependence on BB-SMI6-12-V-P5, qualify BB-SMI6B-12-4-P5, and update sourcing records before channel stock becomes harder to secure.
